I am having some problems setting up Hot Module Reloading in Laravel Mix inside a Docker container.
I have the following Dockerfile:
FROM php:7.4.0-fpm
RUN curl -sL https://deb.nodesource.com/setup_13.x | bash
RUN apt-get update && \
apt-get install -y -q --no-install-recommends \
nano apt-utils curl unzip default-mysql-client nodejs build-essential git \
libcurl4-gnutls-dev libmcrypt-dev libmagickwand-dev \
libwebp-dev libjpeg-dev libpng-dev libxpm-dev \
libfreetype6-dev libaio-dev zlib1g-dev libzip-dev && \
echo 'umask 002' >> /root/.bashrc && \
apt-get clean
# Docker PHP Extensions
RUN docker-php-ext-install -j$(nproc) iconv gettext gd mysqli curl pdo pdo_mysql zip && \
docker-php-ext-configure gd --with-freetype=/usr/include/ --with-jpeg=/usr/include/ && \
docker-php-ext-configure curl --with-curl
WORKDIR /var/www/html
COPY . /var/www/html
EXPOSE 80
Which I am building using the below docker-compose.yml file.
# The Application
app:
build:
context: ./
dockerfile: app.dockerfile
working_dir: /var/www/html
volumes:
- ./webroot:/var/www/html
environment:
- "DB_PORT=3306"
- "DB_HOST=database"
- CHOKIDAR_USEPOLLING=true
# The Web Server
web:
build:
context: ./
dockerfile: web.dockerfile
working_dir: /var/www/html
volumes_from:
- app
ports:
- 80:80
In previous Node.js apps, I have copied over the data inside the dockerfile, and mounted the volume in the compose file, however this doesn't seem to be having the same effect with Laravel.
I am seeing the below output in Git Bash, however the web pages are not reloading with changes at all after I run npm run hot inside the container, not even with a manual refresh:
Despite this, npm run watch-poll, which I have used previously, still works as expected.
Typically I see logs in the console from HMR and WDS inside the browser when viewing the application. However in this situation I am not seeing any outputs.
Below I have also included my webpack.mix.js file. I have been messing around with some of the options, such as the port and host, as I know they need to be configured a certain way when running inside a container. Any help would be appreciated as I am struggling to work out where I am going wrong.
mix.options({
hmrOptions: {
host: 'localhost',
port: '80'
},
});
mix.webpackConfig({
mode: "development",
devtool: "inline-source-map",
devServer: {
disableHostCheck: true,
headers: {
'Access-Control-Allow-Origin': '*'
},
host: "0.0.0.0",
port: 80
},
});
Edit:
Error output when running npm run hot after setting both host values to web:
> @ hot /var/www/html
> cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js
